Facebook connection?
● The next evolution of Facebook Platform
● It enables the integration of the Facebook Platform into your own site, allowing your users to:
– Seamlessly "connect" their Facebook account and
information with your site
– Connect and find their friends who also use your site
– Share information and actions on your site with their
friends on Facebook through their profile pages &
newsfeeds
Facebook to my site?
• Identity: Seamlessly connect the user's Facebook account and
information with your site.
• Friends: Bring a user's Facebook friends into your site. You can
even link friends that have existing accounts.
• Discovery: Publish information back into their friends' News
Feeds on Facebook.
• Privacy: Bring dynamic privacy to your site.
• Reliability: The full power and flexibility of Facebook
Platform.
Should Use Facebook Connect?
• One-click Login: Allow users to log in with their Facebook identity and
allow your site to access their Facebook profile information.
• Increased engagement: Leverage users' personal interests to show more
relevant information and surface personalized content from friends such
as reviews or comments.
• New forms of distribution: Users can share content and actions taken on
your site with friends back on Facebook through feed, invites, and other
social communication channels on Facebook.
Facebook core
Facebook Graph API?
– Facebook's core
– Presents a simple, consistent view of the Facebook social graph
– Every object in the social graph has a unique ID. You can access the properties of an object by requesting https://graph.facebook.com/ID
– People and pages with usernames can be accessed using their username as an ID
– All responses are JSON objects
– Relationships
– Reading, Searching, Publishing, Deleting, Analytics

Technical stepsTechnical steps
First step
• Yêu cầu chung: YOUR_APP_ID
• đăng ký với FB để lấy mã ID tương tác với ứng dụng của FB (FaceBook API)
• http://developers.facebook.com/setup/
Next step : Authentication Authenticate on your site (out of FB). Method of authentication :
in code - server side : The server-side flow is used whenever you need to call the Graph API from your web server
in html - client side : The client-side flow is used when you need to make calls to the Graph API from a client, such as JavaScript running in a Web browser or from a native mobile or desktop app
Iusse request :
https://www.facebook.com/dialog/oauth?
client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=email,read_stream Return code to get access token key:
Kết thúc Authentication thì FB sẽ trả về code để lấy token code và access vào graph protocol của FB để lấy các loại dữ liệu khác
nguồn tham khảo : http://developers.facebook.com/docs/authentication
Reading
Using access token key, issuing HTTP GET requests , return data in json
ví dụ truy cập feed :
https://graph.facebook.com/id/feed?access_token=2227470867|2.AQA_W4-fDdlG-erj.3600.1306126800.0-1090002606|Ktp_XdsULJo0j-CAaUratCxJKqM
Php code:
<?php
$readfeed_url = sprintf('https://graph.facebook.com/%d/feed?access_token=%s',$fbdata['fbid'], $fbdata['access_token'] ) ;
$feed = json_decode(file_get_contents($readfeed_url));
?>
Publishing
Using access token key: issuing HTTP POST requests
Php code tương ứng :
<?php
$token = 3523452345.....
$message = "Hello, Arjun. I like this new API";
$uid = arjun
$url = https://graph.facebook.com/$uid/feed?access_token=$token&message=$message&method=post
$result = file_get_contents($url);
?>
Alternatively, OpenSocial
Market Size and Competition
• Ideally speaking, OpenSocial has a market potential for 250 million users as opposed to 64 million active users on Facebook
• 15,000 Applications on Facebook. Difficult to rapidly grow user base due to a saturated market
• Most existing Google Widgets can run on OpenSocial. Results? Difficult to rapidly grow user base due to existing competition
Technical Differences
• Facebook requires proprietary languages (FBML, FQL, FBJS). Google requires XML and JavaScript
• Google provides an IDE (aka Google Gadget Editor)
• Google hosts applications for free. Facebook doesn’t
Language Support
Facebook API• FBML• FQL
• FBJS
• Partial support for AJAX• Backend languages like
PHP, Java, .NET on Canvas
OpenSocial API• XHTML/XML• JavaScript
• Full Support for AJAX
• Backend languages like PHP, Java, .NET on Canvas
FB and Open social
• The choice of your platform should depend on demographic
• OpenSocial is modeled after Facebook. So if you’ve built a Facebook application before, it is relatively easy to learn OpenSocial
• “Write Once, Run Anywhere” is not exactly true. An Orkut specific OpenSocial app. Might not necessairly run on Hi5
